I had a protected sex with another guy. I took the insertive role. He also fellatioed me, and so did i, but he didnt ejaculate to be specific. Im afraid that i might have contracted hiv. Its been 6 weeks after that encounter. Im feeling a sore beside my neck, i suspected it of being a swollen lymph node, but i hadnt seen nor felt a lump. One of the tip of my toenails also discolored, it became greenish yellowish. Im having a red mark on my chest, but its not definitely i rash. What are the chances that i have contracted the disease. The anxiety is killing me.
